Technic Launcher Won't Open

[Gabin]

Whenever I right Click Technic Launcher to open, my Java icon flashes twice on my dock and then disappears. A blue technic launcher box appeared the first time and I clicked on the recommended folder and clicked install, and ever since it hasn't opened. Are there any solutions or am I screwed?

Im on Mac btw

Ik it's 2019

And the java version you are using is?

[Gabin]

12.0.1 

I've gotten to the technic screen where you click install in the bottom right corner but then the logo didn't pop up and it didn't ask for my account.

I also watched a video and made an automated technic launcher command but got the same result.

Technic Launcher and Java 12 together do not work on Mac. Use Java 8 instead. You will have to remove Java 12.

Okay thanks ill give it a try once I get home.

Edit: I'm having trouble removing Java 12, I paste in the following codes

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin 
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane 
sudo rm -fr ~/Library/Application\ Support/Oracle/Java

but it doesn't seem to work, because when I type -java version, it still says 12.0.1
